The dour face settled into grim determination. "The only sensible thing. Take care of these plants, conserve the air, and squeeze by until we can reseed. And, Dr. Pietro, with your permission, we'll turn about for Earth at once. We can't go on like this. To proceed would be to endanger the life of every man aboard."

"Please, Danton." Jenny put her hand on Pietro's arm. "I know what this all means to you, but—"

Pietro shook her off. "It means the captain's trying to get out of the expedition, again. It's five months back to Earth—more, by the time we kill velocity. It's the same to Saturn. And either way, in five months we've got this fixed up, or we're helpless. Permission to return refused, Captain Muller."

"Then if you'll be so good as to return to your own quarters," Muller said, holding himself back with an effort that turned his face red, "we'll start clearing this up. And not a word of this."

Napier, Lomax, Pietro and I went back to the scientists' quarters, leaving Muller and Jenny conferring busily. That was at fifteen o'clock. At sixteen o'clock, Pietro issued orders against smoking.

Dinner was at eighteen o'clock. We sat down in silence. I reached for my plate without looking. And suddenly little Phil Riggs was on his feet, raving. "Whole wheat! Nothing but whole wheat bread! I'm sick of it—sick! I won't—"

"Sit down!" I told him. I'd bitten into one of the rolls on the table. It was white bread, and it was the best the cook had managed so far. There was corn instead of baked beans, and he'd done a fair job of making meat loaf. "Stop making a fool of yourself, Phil."

He slumped back, staring at the white bun into which he'd bitten. "Sorry. Sorry. It's this air—so stuffy. I can't breathe. I can't see right—"

Pietro and I exchanged glances, but I guess we weren't surprised. Among intelligent people on a ship of that size, secrets wouldn't keep. They'd all put bits together and got part of the answer. Pietro shrugged, and half stood up to make an announcement.
